Title: Dimerisation of benzaldehyde
Post by: limpet chicken on May 19, 2005, 02:48:10 AM

I wish to perform a dimerisation reaction on benzaldehyde, on a small scale, to form benzil, but I cannot find a specific for the dimerisation itself, can anyone help me on this?

Thanks.

Thanks AWK, that is EXACTLY what I was after.

I greatly prefer working with thiamine HCl as the dimerisation catalyst than cyanides, this makes the whole reaction so much easier to perform, and so much safer.
